For speech recognition, one may wish to use as a token a phonetic
equivalent of a word. This may be done by phonetic spelling in the ususal
writing system of the current language, or by external-production-reference
to a speech synthesis grammar production for a more precise phonetic form,
if I understand the architecture.
In any case, it is important to unambiguously capture the relationship to
the standard spelling of a word, if the token represents a word. "The
standard spelling" is meant to indicate "as you should look it up in a
dictionary."
There is an XML precedent in RUBY that could be followed for providing this
capability.
Is this planned to be covered in the 'semantic processing' volume? This is
an important function. Please clarify.
